That's the 1st layer of the support leaking from that supported hole. That is really just a cosmetic, harmless issue, though we may fix it one day.

I figured it might be something like that. It's obviously nothing more than a small annoyance but I wanted to ensure that there was awareness of the issue.

Fixed with 539e80e. Duplicate of #2245

When expanding the 1st layer support layer, do it by small steps while
trimming with object to avoid supports to leak through object walls.
